Animal Agriculture Benefits •  Animal Agriculture accounts for 40% of Ag

GDP. •  Currently employs 1.3 billion people. •  Of the 880 million rural poor people living on

less than $1 per day, 70 percent are partially or completely dependent on livestock for their livelihoods and food security.

•  Global meat production is expected to more than double to 465 million tonnes by 2050.

•  Global milk production is expected to almost double to 1043 million tonnes by 2050.

Meat Consumption on the Rise

Environmental Concerns over Animal Agriculture The argument goes something like this: • As the numbers of farm animals reared for meat, egg, and dairy production increase, so do emissions from their production. • By 2050, global farm animal production is expected to double from present levels. • The environmental impacts of animal agriculture require that governments, international organizations, producers, and consumers focus more attention on the role played by meat, egg, and dairy production. • Mitigating and preventing the environmental harms caused by this sector require immediate and substantial changes in regulation, production practices, and consumption patterns.

•  Grazing and pasture lands account for the 70% of land used in agricultural production (30% of land on Earth).

•  Livestock accounts for 8 % of total human water use, largely from irrigation of crops.

•  Livestock account for an estimated 18 percent of human-caused greenhouse gas emissions.

Human Activities Dominate Earth

Croplands and pastures are the largest terrestrial biome, occupying over 40% of Earth’s land surface
